This Aerospace Standard (part standard for A286 cres) is intended to establish a general specification for the Segmented High-Beam, All-Metal, Self-Locking Hexagon Nuts that are used on T-Bolt tightened V-Band Couplings, band clamps, and strap assemblies. This AS is to be the third of three consecutive AS numbers, the previous two being the design specification and the part standard for type 347 cres.

Rationale

There is a need for a general specification to define these specialized nuts whose basic design has been defined on several supplier drawings, and their manufacturing processes and applications have been well established.
